cousin

Shake a "C" by the side of your head.
This sign is similar to niece/nephew except that it uses a "C" handshape. 

Often students ask if you do it lower (near the cheek) to mean "girl" and higher (near the temple) to mean "boy."
No, there is no distinction.  Just hold a "C" up to the side of your head and twist it twice.
